POS terminals transmit data back to the computers they're attached to unencrypted, so they can definitely store it if they wanted to. Everything is speculation at this point, I assume they just kept CC and personal info in a db somewhere for no good reason like a lot of companies do but it's really hard to tell as Dixons haven't told the media too much currently.
